Forward-Looking Statements

This Current Report on Form 8-K includes “forward-looking statements” within the meaning of the “safe harbor” provisions of the United States Private Securities Litigation Reform Act of 1995. Forward-looking statements may be identified by the use of words such as “estimate,” “plan,” “project,” “forecast,” “intend,” “will,” “expect,” “anticipate,” “believe,” “seek,” “target” or other similar expressions that predict or indicate future events or trends or that are not statements of historical matters. These forward-looking statements also include, but are not limited to, statements regarding projections, estimates and forecasts of revenue and other financial and performance metrics, projections of market opportunity and expectations, the estimated implied enterprise value of the Combined Company, LEADING’s ability to scale and grow its business, the advantages and expected growth of the Combined Company, the Combined Company’s ability to source and retain talent, the cash position of the Combined Company following closing of the Business Combination, HAIA’s and LEADING’s ability to consummate the Business Combination, and expectations related to the terms and timing of the Business Combination, as applicable. These statements are based on various assumptions, whether or not identified in this Current Report, and on the current expectations of HAIA’s and LEADING’s management and are not predictions of actual performance.

These statements involve risks, uncertainties and other factors that may cause actual results, levels of activity, performance or achievements to be materially different from those expressed or implied by these forward-looking statements. Although each of HAIA and LEADING believes that it has a reasonable basis for each forward-looking statement contained in this press release, each of HAIA and LEADING cautions you that these statements are based on a combination of facts and factors currently known and projections of the future, which are inherently uncertain. In addition, there will be risks and uncertainties described in the Proxy Statement/Prospectus included in the Registration Statement relating to the Proposed Business Combination, which has been filed with the SEC, and other documents that may be filed by the Combined Company or HAIA from time to time with the SEC. These filings may identify and address other important risks and uncertainties that could cause actual events and results to differ materially from those contained in the forward-looking statements. Neither HAIA nor LEADING can assure you that the forward-looking statements in this press release will prove to be accurate. These forward-looking statements are subject to a number of risks and uncertainties, including, among others, the ability to complete the Proposed Business Combination due to the failure to obtain approval from HAIA’s shareholders or satisfy other closing conditions in the Business Combination Agreement, the occurrence of any event that could give rise to the termination of the Proposed Business Combination Agreement, the ability to recognize the anticipated benefits of the Proposed Business Combination, the amount of redemption requests made by HAIA’s public shareholders, costs related to the Proposed Business Combination, the risk that the Proposed Business Combination disrupts current plans and operations as a result of the announcement and consummation of the Proposed Business Combination, the outcome of any potential litigation, government or regulatory proceedings, and other risks and uncertainties, including those to be included under the heading “Risk Factors” in the Registration Statement filed with the SEC and those included under the heading “Risk Factors” in HAIA’s Annual Report on Form 10-K for the year ended December 31, 2024, and other filings with the SEC. There may be additional risks that neither HAIA nor LEADING presently know or that HAIA and LEADING currently believe are immaterial that could also cause actual results to differ from those contained in the forward-looking statements. In light of the significant uncertainties in these forward-looking statements, nothing in this press release should be regarded as a representation by any person that the forward-looking statements set forth herein will be achieved or that any of the contemplated results of such forward-looking statements will be achieved. The forward-looking statements in this press release represent the views of HAIA and LEADING as of the date of this press release. Subsequent events and developments may cause those views to change. However, while HAIA and LEADING may update these forward-looking statements in the future, there is no current intention to do so, except to the extent required by applicable law. You should, therefore, not rely on these forward-looking statements as representing the views of HAIA or LEADING as of any date subsequent to the date of this press release. Except as may be required by law, neither HAIA nor LEADING undertakes any duty to update these forward-looking statements.

Participants in the Solicitation

HAIA, LEADING and their respective directors, executive officers and other members of management and employees may, under SEC rules, be deemed to be participants in the solicitations of proxies from HAIA’s shareholders in connection with the Proposed Business Combination. Information regarding the persons who may, under SEC rules, be deemed participants in the solicitation of HAIA’s shareholders in connection with the Proposed Business Combination will be set forth in the Proxy Statement/Prospectus included in the Registration Statement to be filed with the SEC in connection with the Proposed Business Combination. Additional information regarding the participants in the proxy solicitation and a description of their direct and indirect interests will be included in the Proxy statement/Prospectus when it becomes available. Shareholders, potential investors and other interested persons should read the Proxy statement/Prospectus carefully when it becomes available before making any voting or investment decisions. You may obtain free copies of these documents from the sources indicated above.

No Offer or Solicitation

This Current Report on Form 8-K is not a proxy statement or solicitation of a proxy, consent or authorization with respect to any securities or in respect of the Proposed Business Combination, and does not constitute an offer to sell or the solicitation of an offer to buy any securities of HAIA, LEADING or the Combined Company, or a solicitation of any vote or approval, nor shall there be any sale of securities in any jurisdiction in which such offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of any such jurisdiction. No offer of securities shall be made except by means of a prospectus meeting the requirements of the Securities Act of 1933, as amended, or an exemption therefrom.
